## Overview

Prove, founded in 2008, provides phone-centric [identity verification](https://startwithidentity.com/guides/compliance/customer-identity-verification-guide/) and authentication, using phone number intelligence and possession signals to verify and authenticate users with low friction. It is strongest in US financial services, where phone-based trust streamlines onboarding. See all [identity verification vendors](https://startwithidentity.com/vendors/identity-verification/) for alternatives.

## What it is good at

Phone-based verification and authentication that cut onboarding friction are the strengths, backed by deep phone-intelligence data and possession signals. The same signals support ongoing authentication, so Prove spans both verify and login, which is unusual in this category and valuable for banks fighting drop-off. Because possession and phone-tenure signals can verify a returning user almost invisibly, Prove is attractive for high-friction flows like account recovery and step-up where document re-capture would lose customers.

## Where it falls short

Coverage and accuracy depend on phone-intelligence data, which varies by market and is weaker outside the US. It is not a document-first verifier, so buyers needing global document and biometric checks will pair it with another vendor. Pricing is quote-based. Outside its strongest US data markets, coverage thins and the model leans more on supplementary checks, so a global rollout cannot rely on phone intelligence alone.

## Pricing

Quote-based, structured around verification and authentication volume. Model your real volume with the [TCO calculator](https://startwithidentity.com/tools/tco-calculator/). Costs are typically negotiated against verification and authentication volume, with no public list price.

## Best for, and who should look elsewhere

Choose Prove when phone-centric, low-friction identity and authentication fit your users, especially in US finance. For document-first verification consider [Onfido](https://startwithidentity.com/vendors/identity-verification/onfido/) (now Entrust IDV); for fraud and device signals consider [Sardine](https://startwithidentity.com/vendors/identity-verification/sardine/); for US synthetic-fraud detection consider [SentiLink](https://startwithidentity.com/vendors/identity-verification/sentilink/).

## Bottom line

A strong phone-centric identity and authentication choice, especially for US financial services.
